I wrote these questions that mix together direct and inverse proportion because I couldn't find any elsewhere. Plenty of textbooks contain the unitary method and questions about builders building walls but none mix these ideas together.
Partly inspired by the question about 8 machines making bottles on the Edexcel GCSE non calc mock.
My classes always find direct and inverse proportion easy separately, but find these questions very challenging. Use with high ability or as a challenge for KS3 classes.

This was exactly what I wanted. Unfortunately there's no answers so only 4 stars but the questions are great. Thanks.
This is a good resource. It is just that I am looking for basic questions based on real situations
